What does a brake wear sensor do?

A brake wear sensor is a small electronic component that attaches to your brake pads. When the brake pad material wears down to a specific point, the sensor makes contact with the brake rotor, triggering a warning light on your dashboard to alert you that your pads need to be replaced.

Why should I replace the wear sensor when changing brake pads?

It's a good practice to replace the wear sensor whenever you replace your brake pads, especially if the old sensor is brittle or damaged. This ensures the warning system will function correctly and helps prevent you from accidentally damaging your new brake pads or rotors.

Product Details

When you're working on the brakes for a BMW 7 Series or M5 from the late 80s to mid-90s, these wear lead sensors from EBC are a small but important part of the job. Their main purpose is to let you know when your brake pads are getting thin and need replacing. Without them, you might not realize your pads are worn down until they've damaged your rotors, which is a much more expensive fix.

This particular sensor is designed to fit a range of BMW models, including the 735i, 740i, and the M5. It's a simple, well-built component that connects to your brake pad and makes contact with the rotor when the pad material wears down to a certain point. This contact triggers a warning light on your dashboard, giving you a heads-up before you grind metal-on-metal.

It's a good idea to replace these sensors whenever you're doing a brake job, especially if the old ones are brittle or damaged. They're an inexpensive way to protect your rotors and ensure your braking system stays in good working order.
